By the 1960s, Sears realized that its customers expected the colors printed in its catalog to be spot-on correct. As its VP of catalog sales noted, "Your grandmother will hold the catalog up next to her curtains to see if the colors match. If they match, she will order new sofa cushions. If when the sofa cushions arrive they do not match the curtains, she will return them angrily and stop buying from Sears for a while. The colors in the catalog must be exact." By the time I got involved, Sears catalogs were all printed by R. R. Donnelley & Sons at its printing plant on Calumet street in Chicago. RR Donnelley won and kept the contract because they were able to do a better job of printing accurate colors than the competition. My involvement was advising them on digital color separation technology so they could use 7-color presses; the classic optical separation process didn't work well past 4 colors and the filters were mind-numbingly expensive. When my mother buys sofa cushions by mail order, she evaluates their color using the screen on her iMac. Even if she could lift it to hold it next to her curtains, proper comparison of glowing-screen colors with fabric colors is impossible. The catalogs were better. I sometimes wish I had kept one.

LR has good reasons for requiring the catalog to be local, and unless you have a black belt in computer and network wrangling, you won't be able to dig yourself out of the mess made when something goes wrong. I've tried it, and decided it was too risky. And it was a lot of work to clean up the destruction when it failed.

Shared-master index catalogs are difficult under any circumstances, but Lightroom makes it worse by postponing as much processing as it can. The software engineers chose this technique to make the app seem faster. You have certainly seen one kind of lazy evaluation when you export a photo in LR. It doesn't export right away. It launches the export process and then returns to ask you what you'd like to do next. If you try to quit the Lightroom app before the export is done, it scolds you and tells you to wait. Much of the other processing is also "lazy", which is to say that it doesn't happen when you ask for it but rather happens when LR gets around to it. The most insidious effect here is if the process that is running lazily in the background needs to do semaphore locking on the master catalog, and there is a siphon running somewhere that is moving the catalog file somewhere else, the locks will get replicated to the destination. Semaphore locking is the core technology of multicore/multi-thread/multi-processor computing. Here is the usual classroom explanation, showing two processes that are each trying to add 1 to a number. Process 1: get the number from memory add 1 to it store it back into memory Process 2: get the number from memory add 1 to it store it back into memory The problem arises if those two processes are running concurrently in separate threads. It can look like this: Process 1: Process 2: get the number from memory get the number from memory add 1 to it add 1 to it store it back into memory store it back into memory Often this results in only one addition, not two. So you have to lock the memory: check to see if the memory is locked. If it is locked, then wait. lock the memory location get the number from memory add 1 to it store it back into memory unlock the memory location The "if it is locked, then wait" was the topic of at least a dozen PhD dissertations in computer science in the 1980s. The famous Mac "spinning pizza of death" is what shows on your screen when a process is waiting for a lock on something bigger than a single number. Usually the spinning pizza shows it waiting for an entire file to be unlocked. If you are so unlucky as to copy a master catalog to another place when there is a file lock set, then the next time LR ties to use the copied master, it will see the lock in the copy and wait for it to cleaR. But that wait will be forever, because the would-be unlocker doesn't know that the copy has been made and doesn't notify that destination. Eternal SPOD.

Yes but. It would normally work, but it is a bad idea to separate a LR catalog from its images. For this technique to work with 100% safety, you would need to sync over not just the main LR catalog but all of the associated images. Dropbox will do this reliably as long as you are careful to check the Dropbox sync status each time you launch LR, but Dropbox has a limit of 3TB for most of its plans and most of those plans are hundreds of dollars per year.
